Los Angeles Intl (LAX) in Los Angeles, CA.
Where to walk your dog:
Los Angeles International Airport (LAX) has a small Pet Park at the southeast end of the Central Terminal Area near Terminals 7-8 (United Airlines) where pets can take a potty break. There's a little dog house there and a stand with plastic bags so owners can clean up after their animals, and a trash can. Pets cannot run free (i.e., unleashed) because it is still in the Central Terminal Area and the roadway runs along side it.
There are new pet areas between terminals 1 and 2. as well as across from terminals 5 & 6 in the grassy area.
Additional areas are under construction.
